Caleffi FlowCal™ 127359AF 3G0 Compact Dynamic Balancing Valve, 3/4 in, C, 3 gpm, Brass Body

The FlowCal™ compact dynamic automatic flow balancing valve is pressure independent and maintains a fixed flow rate within varying system differential pressure ranges. It eliminates the need for onsite measurements and trial and error flow rate settings as required with manual calibration valves. The design incorporates an exclusive flow cartridge, made of an anti-scale, low noise polymer and a compact low-lead brass valve body for use in hydronic and domestic water systems. The FlowCal™ balancing valve is available with NPT male, sweat or press union connections. Presscon™ copper tail-piece with union nut makes installation and maintenance fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing if unpressed and provide a perfect leak proof seal when completely pressed.
